Specification of Letters Patent.

Patented Apr. 2, 1912.

Application led December 7, 1910. Serial No. 596,148.

To all lwhom it may concern.'

Be it known that I, ERNEST OLDENBUscH, a citizen of the United States, and a resident of the cit of New York, borough of Brooklyn, in t e county of Kings andpState of New York, have invented a new and Improved Book-Rack, of which the following is a full, clear, and exact description.

This inventlon relates tocertain improvements in book racks, and more particularly to that t pe of book-rack disclosed in my previous atent No. 952,839 granted March 22nd, 1910.

The Imain object of my present invention is to simplify the joint or connecting means between the base and the end wall so that all of the parts may be made solely of sheet metal and the cost of manufacture thus materially reduced. By forming the book rack in accordance with my present invention, a smaller number of pieces or parts are necessary and thus the work of assembling is reduced and the liability of parts becoming accidentally. detached is reduced.

A further object of my invention is to provide a better support for the rack, when the ends are folded down.

A still further object is to more eii'ectively support the base between the end walls when the book rack is extended to its maximum extent.

Other objects and advantages will beset forth more fully hereinafter and the scope of the invention particularly defined in the claims.

Reference is to be had to the accompanying drawings, formingva part of this specilication, which similar characters of reference indicate corres onding parts in all the figures, and in which- Figure 1 is a perspective view of a book rack constructed in accordance with my invention; Fig. 2, is a lon itudinal section through the book rack. Fig. 3, is a trans- -verse section and Fig. 4 is a perspective view of a portion of the base.

In the book rack illustrated in the accompanying drawings, I provide two end walls l10 and 11 and a base made up of separate extensible members 12 and 13. Each extensible member is formed of two telescoping channels 14 and 15, each formed of sheet metal substantially as illustrated in my previous patent. The most important feature of my present invention relates to the means for connecting these channels to their respective end walls. To do this, I employ a. transversely extending member 16 formed of sheet metal so bent as to present a substantially flat base portion 17 and a tubular portion 18. The base portion 17 forms the bottom of the tubular portion and the latter is approximately semi-cylindrical in form. One lower edge of the sheet metal forming the tubular portion terminates in engagement with the upper surface of the-base and at the opposite edge of the tubular portion, the metal forms substantially a right angle 20. The two channels 15 rest upon the upper surface of the base portion 17 and extend transversely through the tubular portion as is indicated particularly in Fig. 2. The ends of the channels are thus concealed inside of the tubular portion and are su ported directly on the base. The channdls are preferably held in place by solder, not shown. The other two channels of 14 are secured within the other tubular member in exactly the same way. It will thus be seen that the two channels 15 are rigid with each other as are also the two channels 14.

Each end wall is formed of sheet metal and at its end edges has flanges bent to form the sockets, which receive the ends of the tubular members. As illustrated, each socket is formed of a substantially semicircular flange 21 bent to lie at substantially right angles to the end wall and along the periphery of each flange 21 is a marginable flange 22 at right an les to its corresponding flange 2l. The an es 22 extend toward each other and toget er with the flanges 2l and the end Walls 1l form sockets or pockets into which the ends of the tubular members extend. To facilitate the rotation of the tubular members within the sockets recesses 23 and 24 may be cut in the lower corners of the tubular member, as indicated in Fig. 4.

Itl will be noted that the angle or corner 20 on the tubular member constitutes a stop which prevents the end wall from swinging outwardly beyond a vertical position and that the end wall may readily be folded downwardly, so as to lie on top of the channels. The entire book rack, except for the stops and supports hereinafter referred to, is made of only eight pieces of sheet metal, four of which constitute the channels or base proper, two the end walls and sockets supports.

they become worn or injured, and

and the other two, the tubular members, which connect the channels to each other and connect the channels to the end walls. p

For supporting the book rack and preventing the latter from scratching or marrin a table or book-case, upon whlch the boo rack may be placed, I provide. legs or Each leg as illustrated lncludes a sheet metal collar 25,.encircling a body or core 26 of rubber cork or other suitable material. The screw 27 extends down through each base flange 19 adjacent its vends and into the core. The screws may be placed in position before the parts are assembled and the supports may be readily screwed on afterward. The supports are very easily removed and replaced by new ones, in case they are very inexpensive to manufacture. It will be noted that the supports are not moved during the folding down of the end walls, so that they still act as supports when the book rack is collapsed, which is not the case in the construction shown in my previous patent. v

To prevent the channels 15 from being pulled out of the channels 14, I provide suitable stops which include depending flanges 28 on the free ends of the webs of the channels 15. These extend slightly below the lower edges of the channels, as is indicated in Figs. 2 and 3. Each outer channel 14 has a transverse wall 29, soldered thereto, and each of these walls has an upwardly extending tongue 30,- which contacts with the corresponding flange 28, when the book rack is extended to the maximum point. Each wall 29 carries a support, which is preferably identical with the supports above referred to. Thus, when the book rack is extended to the maximum position, the book rack is supported not only at its ends but also midway between the ends. This removes any strain on the parts and resists any tendency to bend the channels.

Vlower side terminating inl a horizontal flange, said tube having apertures in the side thereof above said flange to receive-theends of said members and support them on said flat lower side and an end wall h aving flanges integral therewith and bent to engage with the ends of said tube to form a pivotal connection therewith.

2. A. book rack having two parallel book supporting members, a transversely extending tube of sheet metal and presenting a substantially hat lower side, sald tube having apertures in the wall thereof directly above said flat lower side and receiving the ends of said members to support them on said Hat lower side and an end wall having flanges bent to'engage with the ends of said tube -to form a pivotal connection therewith.

3. book rack having two parallel book supporting members, a transversely extending tube of sheet metal having apertures in the side thereof receiving the ends of said members to support them and an end wall.

having flanges bent to lie parallel with each other and in engagement with the ends of y said tube and each of said anges having a marginal iange partly encircling said tube whereby said end wall is pivotally secured to said tube.

In testimony whereof l have, signed my name to this specification in the presence of two subscribing witnesses.
